Recent technological advances enable shooting and displaying video sequences with UHD-TV quality, nevertheless internet and broadcast networks do not always provide suitable bitrate. Hence the importance to improve data broadcasting technologies, in particular video compression which through HEVC allows halving the transmission rate for the same visual quality.
HEVC is a new video coding standard which is going to replace current MPEG-4 Advanced Video Coding (MPEG-4 AVC/H.264).This is the result of a work that international experts carried out in the context of a joint committee between MPEG (ISO) and ITU (International Telecommunication Union).This technology allows to provide image quality equivalent to that of MPEG-4 AVC, but with better data compression, generally half of the bitrate, thus facilitating the dissemination of UHD-TV images.
With more than fifty contributions to standardization organizations, the 4EVER team has cooperated extensively to the standardization of this new video coding standard, saving bandwidth. Standardized by the ITU in January 2013, HEVC can halve the transmission rate of coded video with no loss of visual quality.
Four months after the standardisation of HEVC, during the “Roland Garros” French tennis open tournament, the 4EVER partners demonstrated the first live end-to-end operational MPEG-HEVC chain with the development of prototype real time encoders and decoders on TVs and tablets.
